I have had this Scan Gauge for over three years now and I use it in my Dodge diesel, Honda CR-V and Jeep Commander. It is simple to use, just plug it in and choose what you want to
monitor. I also use it to scan for trouble codes on my friends vehicles. I had one small problem with the gauge giving a false reading on RPM. Warranty had expired and when I contacted the mfg, they requested the unit. It was repaired and returned and the best no charge. Very impressed with Customer Service and Scan Gauge.

Awesome tool to have, especially for heavy towing

Only reason it's not a five star, the mounting design is horrible, velco strips (very tempermental, for the money I expected more). Regardless, the commputer itself is outstanding. I use it on a Ram 2500 TD and it is far more accurate than the factory gauges. As far the values not displayed by the factory dashboard that it reads for you and if you are tow a 5th wheel, it's a must have! It monitors performance factors you should be aware of, especially in varying climate and terrin.

Bought it for a 2009 Winnego Adventure, ford v-10, couldn't get it to communicate so I tried it on my 2004 nisson frontiere and it worked great. Contacted the manufacture and was told that it should work, it doesn't returned it. If someone can tell me how to get the gauge to work in my rig I'll buy it again. Great versitility.

It's a snap.

I installed the gauge the same afternoon I received it. I have not had the opportunity to
fill
the tank or set the speedometer calibrations, but the instruction book that came with
the
instrument is well-written and I anticipate no problems. I had some difficulty finding the
OBD port, but once found the connections were very easy to accomplish and I was able
to view data on the scan gauge almost immediately. If the gauge is mounted so that the
input is to the side input port instead of the port located on the back of the instrument, I
recommend replacing the included velcro mounting strips with more substantial strips
purchased at a home improvement store such as Home Depot or Lowes.

I purchased ScanGaugeII and had a mechanic hoock up the wire. Plugged in the unit and within seconds it was functioning. I wanted to monitor the tempature of the transmision fluid. The code was listed at the web site for my chevy van. The temp guage worked great. I also have instant MPG and average MPG. If I drive to the guage I
know I am getting better gass milage.

The ScanGauge II works very well. It was a plug-n-play for my Winnebago Via on the sprinter chassis. Set up was clear and quick. A lot of nice features and logs. Can display four values at a time. Used double sided tape to mount mine to the dash.A good addition to the modern computer controlled RV. Nice to read the codes without going to a shop.

I've had my Scangauge ll for about two years. I purchased it to fill in the factory lack of essential gauges. I have an older Ford chassis on my Class C motorhome. The factory never installed a tachometeron my dash and I really needed to know when to downshift coming down steep hills. This worked fine. I also programmed it to read average mpg, transmission temperature and air intake (outside) temperature. I have also had a peoblem with the 'check engine' light coming on after refuelling. I found it was a dirty EGR valve and was able to fix the problem as well as reset the light. Great tool for a reasonable price.I would recommend it for any vehicle owner interested in what is going on inside their drivetrain.

When I bought my RV with a V10 engine, I was concerned about
gas consumption. I have been pleased to be able to follow
all my data while driving rather than figuring it out after
the fact. RPM, Average MPG, real time MPG and MPH are
constantly being update in front of me, so I can control
performance. I believe it has paid for itself already in
just 3 months.

Great Product

Shipping was fast and the unit was properly packaged. Instructions were easy to
understand, set-up took less than 10 minutes, in fact, it took me longer to figure out how I
wanted to route and secure the cable!! I have a 2013 F-53 chassis with a V-10 engine.
Highly recommend for RV or towing!

Works As Advertised

This product works as advertised and I would make the same purchase again. The unit
is easy to install and use. It provides the information I have been looking for. There is
much more trip information available than I need, but one is not required to use the trip
features. It is the engine data that is important.

My opinion GREAT PRODUCT

My recommendation is for anyone who has a motorhome and knows a little bit
about engines and how they work should get one of these units and install it on
their couch, it does exactly what the advertisement says it will do and there is
more that it will do when you get the unit and read the instructions booklet, take
my word this is a great unit so far and I will rely on it for much information about
my engine.

will it give transmission temperatures for motor homes?

1 answer(s)

by AnonymousDecember 01, 2015

The ScanGaugeII can track transmission temperature through the programmable X-Gauge feature, but only if the vehicle is equipped to do so in the first place. Not all gasoline vehicles have sensors to track transmission temperature or transmission fluid. X-Gauge programmable commands can be viewed here.

Generally, yes, it will work in most vehicles manufacturered after 2004. The requirement is that the vehicle have the OBDII port under the dashboard assembly for this to plug into.
